Question

Which equation represents the polynomial function with zeros –3, 1, and 2, and a y-intercept of –12?

Answer 1

To generate the equation we set up the factors
(x+3) * (x-1) * (x-2) which equals
x^2 + 2x -3 * (x-2)
x^3 +2x^2 -3x -2x^2 -4x +6  equals
x^3  -3x -4x +6 which equals

x^3  -7x +6
